The Pocket Card software empowers mobile device users to access VA data needed to do their jobs, in the form of electronic "pocket cards". There shall be a public client portion of the system (an app for mobile devices), and shall have an application management portion. The public and administration parts of the system utilize two similar client/server models. Both models utilize a common backing database for user and application data storage.
The public client utilizes a mobile application, with content served by a Node web server. The application management piece uses a Node web server / browser client backed by a data store. All servers reside in the VA Mobile Application Environment (MAE), while authentication for administrators would be provided by an IAM service set up for this application. In this way, no public users are directly accessing the VA network for routine use.
